Shading device having at least one awning

ABSTRACT

A shading device having at least one awning and having at least one winding device, which is provided for winding and unwinding the awning and which has a rigging that is stretched taut along a side or a diagonal of the awning, which rigging is rotationally coupled to the windable and unwindable awning. In order to embody this shading device in a particularly durable fashion, it is proposed for the rigging to be embodied as torsionally rigid or low-torsion and for it to be rotationally coupled to the awning over the entire length of the side or diagonal of the awning.

FIELD OF THE INVENTION

The invention relates to a shading device having at least one awning andhaving at least one winding device, which is provided for winding andunwinding the awning and which has a rigging that is stretched tautalong a side or a diagonal of the awning, which rigging is rotationallycoupled to the windable and unwindable awning.

BACKGROUND OF THE INVENTION

There are shading devices known from the prior art with winding devices,which are embodied in the form of a roller-furling device for windingand unwinding an awning. To this end, the winding device has a riggingembodied as a steel cable, which is stretched taut along a diagonal ofthe awning and is rotationally coupled to the awning. By activating ajib furler of the winding device, the rigging is rotated and as aresult, the awning is either wound or unwound by the rigging. It isdisadvantageous that an awning cannot be wound in a crease-free way witha roller-furling device, which can result in increased mechanicalstresses on the awning and damage to it.

There are also known shading devices (EP2216461A2), which are able towind and unwind an awning in a comparatively crease-free way by means ofa rigid winding shaft on a winding device. Such winding devices,however, are comparatively complex from a design standpoint.

SUMMARY OF THE INVENTION

The object of the invention, therefore, based on the prior art describedat the beginning, is to improve the durability of a shading device witha windable and unwindable awning on a rigging. In addition, the shadingdevice should be embodied simply from a design standpoint.

The invention attains the stated object in that the rigging is embodiedas torsionally rigid or low-torsion and is rotationally coupled to theawning over the entire length of the side or diagonal of the awning.

If the rigging is embodied as torsionally rigid or low-torsion, then therigging is able to withstand imparted torques with comparatively littletorsion and thus similarly to a rigid winding shaft known from the priorart, can ensure an even winding and unwinding of the awning on thewinding device—even in those cases in which the rigging is embodied forrelatively wide awnings with a comparatively large span. This danger ofcreasing can be further reduced if the rigging is rotationally coupledto the awning over the entire length of the side or diagonal of theawning. Such a rotational coupling can specifically prevent a relativemovement of the rigging in relation to the awning and thus prevent theawning from twisting over course of the side or diagonal. This ensures acrease-free winding and unwinding of the awning. According to theinvention, therefore, with the given design simplicity of the windingdevice and using a torsionally rigid or low-torsion rigging, a shadingdevice can be produced, which can also have a high durability of theawning. The design according to the invention also makes it possible forthe awning to be detached from the shading device and mounted on it in auser-friendly way. It is thus possible, for example, for the awning tobe easily and safely stowed over the winter months.

A particularly durable rotational coupling between the rigging andawning can be produced if the rigging is sewn and/or glued to the awningover the entire length of the side or diagonal of the awning. It is thuspossible to ensure a durable, crease-free winding and unwinding of theawning.

Another design simplification of the winding device can be enabled ifthe rigging is embodied as a rope. In addition, such a rigging composedof a plurality of oppositely twisted strands can be particularlytorsionally rigid. Preferably, the rope is embodied as a fiber rope inorder to withstand high mechanical stresses and thus further increasethe durability of the device.

Preferably, the fiber rope has a kernmantle braiding with a polyesterbraided sheath and an HPPE (high performance polyethylene) braidedcore—which can ensure a particularly durable rigging.

If the shading device has a belt that extends along the side or diagonalof the awning and is firmly attached to the awning, with the riggingextending between the awning and the belt, then it is possible toproduce a compact, flexible shaft, which can be particularlyadvantageous with regard to the crease-free winding and unwinding of theawning. If the belt is embodied as a webbing, then this makes itpossible for it to be durably attached to the awning, even when powerfultensile forces are exerted on the rigging.

The design of the winding device can be further simplified if therigging is sewn to the belt.

If the belt is sewn to the awning, then not only can they be attached toeach other in a simple way, but it is also possible to further increasethe durability of the shading device.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 2 is a sectional view along line I-II in FIG. 1.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 shows an example of a shading device 1 with an essentiallyfour-sided awning 2 and a winding device 3. The winding device 3 is usedfor winding and unwinding the awning 2, which can be stretched taut bymeans of tensioning ropes 4, which are attached to opposite corners ofthe awning 2 and are part of a tensioning device that is not shown indetail. In the exemplary embodiment, the winding device 3 is embodied inthe form of a roller-furling device and for this purpose, has a jibfurler 5 and a halyard swivel 6 between which a rigging 7 is stretchedtaut, which can be acted on in a rotation direction 8 by means of thejib furler 5. Since the rigging 7 that is stretched taut along adiagonal 9.2 of the awning 2 is rotationally coupled to the awning 2,the awning 2 can be rolled up or unrolled depending on the rotationdirection 8 of the opposing rotation directions of the winding device 3.

According to the invention, the rigging 7 is embodied as torsionallyrigid or low-torsion and therefore has no torsion or hardly any and hasa high torsional rigidity in the rotation directions 8—which preventsthe awning 2 from twisting relative to the rigging 7.

In general, it should be noted that such a rigging 7 can be a fiber ropewith a kemmantle braiding in order to thus ensure the high torsionalrigidity. For example, fiber ropes of this kind are used as a luff linefor a head sail, gennaker, etc. Preferably, such a torsionally rigid orlow-torsion fiber rope with a kernmantle braiding can, for example, havea polyester braided sheath and an HPPE (high performance polyethylene)braided core.

In addition, the awning 2 is rotationally coupled over the entirediagonal 9.2 of the awning 2—as is clearly indicated in FIG. 2 by thefact that the rigging 7 is indirectly attached to the awning 2 by meansof indicated seams 10, 11. This is indirect in that a belt 12, which issewn to the awning 2 by means of seams 10, is sewn to the rigging 7 bymeans of seams 11.

FIG. 1 also shows with dashed lines that the rigging 7 can also beprovided extending along a side 9.1 of the awning 2. Apart from thelateral dimension, this embodiment variant is designed identically toone with the diagonal span. Here, too, the rigging 7 is rotationallycoupled to the awning 2 over the entire length L of the side 9.1 of theawning 2—which makes it possible to achieve a particularly durablerotational coupling between the rigging and awning.

This belt 12 embodied as a webbing 12.1 extends along the same diagonal9.2 as the rigging 7 so that the rigging 7 can be enclosed between thebelt 12 and the awning 2. This protects the rigging 7 on the onehand—and can also achieve a particularly rugged rotational coupling ofthe rigging 7 to the awning 2.

A gap between the rigging 7, the awning 2, and the belt 12 can be filledwith adhesive 13 in order to thus increase the durability of theflexible winding shaft with a rigging 7.
